To produce Clutha glassware, a worker used a gather of pale ruby or pale yellow glass, then rolled it over a marver lightly sprinkled with bits of colored glass and mica flakes. The gather was reheated and blown and tooled into the finished product. It was originally made by James Couper & Sons, Glasgow. It is called "Clutha" from Gaelic for "cloudy." ]]></termNote><termCreatedDate>2026-03-30 20:41:09</termCreatedDate><relation><relationType>UF</relationType><termId>31375114</termId><termName>glass, Clutha</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31344445</termId><termName>glass by technique</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31375152</termId><termName>cloudy glass</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31412053</termId><termName>Cluthra glass</termName><termType>PT</termType></relation></term>  </Zthes>
